Title:
OPTICAL TERMINAL MULTIPLEXER, CONTROL METHOD, AND WAVELENGTH DIVISION MULTIPLEXING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/062139
Kind Code:
A1
Abstract:
Disclosed are an optical terminal multiplexer, a control method, and a wavelength division multiplexing system for reducing a link insertion loss and improving system performance. The optical terminal multiplexer in the present application comprises: a (C+L) waveband optical signal demultiplexing unit, a (C+L) waveband optical signal multiplexing unit, a C waveband optical amplifier, a first L waveband fiber interface unit, a second L waveband fiber interface unit, an L waveband optical amplifier, and an L waveband optical monitoring unit, wherein two fiber interface units of an input end and an output end of the C waveband optical amplifier are removed, and the C waveband optical amplifier can filter a crosstalk L waveband optical signal, so that insertion losses of the two fiber interface units of the input end and the output end of the C waveband optical amplifier are eliminated in the optical terminal multiplexer so as to improve the system performance.
